havainvented an Improvement'inSeparable -Fasteners,: of whichsthefollowing description, in connection with the accompanymg drawing, is a specification, like characters on the drawingrepresenting like parts. 1 :This'invention relates to se arablefasten- 1 ers comprisinga socket mem er and a stud member adapted to be entered into the socket member and. locked therein, and partlcularly to fasteners of this typewhichare provided with means for automatically ejecting the stud-fromthe socket memb h th Stud is released. vs a The object of; the present invention is to provide anstud-ej ecting means which 1s carried by or associatediw ith the stud member.

In order to give an understanding of my invention, :1 have illustrated in the drawings some selected embodiments thereof which will now be described, after which the-novel features thereof will be pointed out in the appended claims.

In the drawings, Figure 1 is a vertical section through a fastener embodying my invention;

Fig. 2 is a View of one of the stud-retaining members;

Fig. 3 is a section on the line 33, Fig. 1;

Figs. 4 and 5 are views showing two different types of stud members embodying my invention.

The stud member comprises a base portion from which extends a stud having a shank 1 and head 2, the head being shaped to present locking shoulders 3 on the under side thereof. The body to which the stud member is secured may have various shapes without departing from my invention. In Fig. 5 I have shown a stud member in which the body is in the form of a plate or disk 4; having attaching prongs 5 extendin therefrom which may be mserted through t e material or part 6 to which the stud member is to be fastened and may then be clenched over to lock the stud member in place. In Fig. 4 I have shown a construction wherein the body of the stud member is in the form of a screw 7 which may be screwed into the part to which the stud member is to be sflcureda v The socket member is shown as having a casing comprising the shell Sand the disk 9,

said disk forming the bottom. of the, casing. This disk 9 is provided with astud-receiving aperture 10-and the top of the shell is also provided withan aperture 11 through which the head of the stud may project. The disk 9 is retained in the shell by means of fingers 12 formed on the shell and which are bent to overlie theunderside of they disk. The socket member maybe secured to .the

part or material 13 to which it is to be attached in'any suitable way, as,. for instance, by means of attaching prongs 14.

15 and 16 indicate two oppositely-disposed stud retaining members which are slidably mounted in the-casing. While these mem bers might have any suitable construction, I prefer to make them duplicates, and each of the'shape shown in Fig. 2. Each retaining member is formed with the body portion 17 and with the stud-engaging portion 18 which is connected to the body portion by the connecting portion 19. Each body portion is also formed with a guiding slot 20 and the stud-engaging portion is provided with a guiding finger 21 and also with the stud-receiving notch 22. With this construction when the two stud-retaining members are in position the stud-engaging portion 18 of each member occupies the opening 23 of the other member, and the guiding finger 21 of each member is slidably received in the slot 20 of the other member. The two studretaining members are acted upon by springs 24 which tend normally to move them into operative locking position. The stud may be released by simply pressing inwardly on the outer ends of the stud-retaining members.

The present invention relates particularly to means for automatically ejectmg the stud from the socket member when the stud-retaining members are manipulated to unlock the stud, and it comprises a stud-ejecting member which is permanently carried by the stud member instead of by the socket member. A simple device adapted for this purpose is shown in the drawings and comprises a stud-ej ecting spring 25 which encircles the shank 1 of the stud and is confined between the body thereof and a collar 26 loosely mounted on the stud.

The collar 26 is retained on the stud when the la er is withdrawn fr m the so k t member by engagement with the shoulder 3 of the stud and t When the studis inserted'into the socket member, the collar 26 will engage either the socket member or the material ldand theas 25, will be compressed, asshown in ig.'1.' When the stud-retaining members stud, the resiliency of the spring 25 will rve' to withdraw the stud from the socket -member automatically. r y "While I have illustrated-herein some se- 'f'lected embodiments of my invention, yet do not wish to'be'limitedto the construc-* 'g'tional features shown.

'- I claim: 9

- 1. In aseparab1e fastenenthe combination with a stud member, of a socket member, stud-retaining means carried by the socket men1b'er, and means permanently'carried by the stud member for automatically withdrawing the stud from the socket member when the stud'isreleased.

2. In a separable fastener, the combination with a stud member, of a socket mem- 'ber, stud-retaining means carried by the -so cket member, a stud-ejecting spring carriedby the studmember, and means-to re tain' said sprin'g'on the stud member when the latter is separated from the socket mam-- ber. Y W
